Actually that is the way the tort law is practiced and works;
All Parties in the Chain of Distribution
As a general principle, you want to include any and all parties involved in the
chain of distribution (the path that the product takes from manufacture to distribution to the customers) of the injury-causing product.
More so
With goods subject to strict liability is usual for the parties in the chain to have overlapping insurance policies; this overlap allows the insurance to be affordable.
The distribution method here;
Like most "silicon valley innovations" crowdfunding evade established business processes thereby adding some confusion into the litigation. Eventually, Indigogo and Kickstarter will be sued on this kind of issue. The issue to prove is whether or not they are in the chain; and to what extent they were involved in "the process." Indigogo was clearly notified that there were issues and concerns with this offering and they failed/refused to act, there is some indication that they were closely involved in the process , the coordination with Sondors and Agency 2.0 These are legal points that would have to be argued.
A death, which I anticipated on this very forum (and well documented herein), is just the kind of case where the effort of litigating against Indigogo and Kickstarter would be monetarily justified.
You are never going to collect money from Sondors, there is no insurance, so the only party in the chain to go after with deep pockets would be Indigogo and Kickstarter.
If you bought a bike you are in a very poor risk position (even if the bike is working for your technically, and you enjoy it).
Nothing could be done against the wave of consumer frenzy; it boils down to fact resistant humans.
“These humans appear to have all the faculties necessary to receive and process information,” Davis Logsdon, one of the scientists who contributed to the study, said. “And yet, somehow, they have developed defenses that, for all intents and purposes, have rendered those faculties totally inactive.”
More worryingly, Logsdon said, “As facts have multiplied, their defenses against those facts have only grown more powerful.”
--that is the case here where retractions, lawsuits, and now a death are factual items of irrelevance.
